Web 2.0 applications often have accessibility and usability problems because of the limitations of (X)HTML. The W3C’s standards draft for Accessible Rich Internet Applications (ARIA) addresses those limitations. It provides new ways of communicating meaning, importance, and relationships, and it fills gaps in the (X)HTML specifications and increases usability for all users by enabling navigation models familiar from desktop applications. Best of all, you can start using ARIA right away to enhance the accessibility of your websites.

ARIA, formerly known as DHTML accessibility, is an up-and-coming standard being developed at W3C - World Wide Web Consortium. All documents are available on the Protocols and Formats Working Group public page. This includes the ARIA roadmap, the ARIA roles spec and the states module.

The Roadmap for Accessible Rich Internet Applications (WAI-ARIA Roadmap) addresses the accessibility of dynamic Web content for people with disabilities. The roadmap outlines the technologies to map controls, AJAX live regions, and events to accessibility APIs, including custom controls used for Rich Internet Applications. The roadmap also outlines new navigation techniques to mark common Web structures as menus, primary content, secondary content, banner information and other types of Web structures. These new technologies can be used to improve the accessibility and usability of Web resources by people with disabilities, without extensive modification to existing libraries of Web resources.
